OPTICAL
Geometric Optics
-
-
bend, and in particular circumstances may split in two, at the interface between two dissimilar media
-
Reflection
direction of the reflected ray is determined by the angle the incident ray makes with the surface normal
-
-
Diffraction
diffraction from a single slit-When light passes through a single slit whose width w is on the order of the wavelength of the light 
intensity in the single-slit pattern
multiple slits-arrangement is presumed to be constructed from a number of identical slits,
the diffraction grating- optical component with a periodic structure that splits and diffracts light
Interference
interference and coherent sources- when the waves emitted from them have the same frequency and constant phase difference
two-sources interference of light-results when light from two sources meets up while traveling through the same medium
-
SUMMARY: optics is the study of how light interacts with materials.we can learn about how the images formed and the shape of a material and the angles at which light rays hit it.
